This invention relates to certain improvements in roll handlingmechanisms for paper winding machines. l

In paperl winding machines, particularly f those used for winding thelarge web rolls produced by Fourdrinier and like paper making machines,the rolls are wound on a spindle` in a winding mechanism, which consistsof a pair of driven Winding rolls, around one of which the'web passes,lthe web roll resti Where lit may be .prepared for shipment or otherwisehandled. Ordinarily the web rolls are lifted from the winding mechanismby suitable devices taking hold of the core or spindle. In large papermakingv machines where the web rolls are wide, particularly thoseproducing web rolls for ynev'vs print,

the rollsvare Vvery. large and heavy, and liftv ing them from the Winderby Ymeans of-overhead hoisting apparatus takes" up a great amount oftime and isfundesirable for other reasons. Furthermore, the spindleonwhich the paper is wound is limited in diameter and "is, therefore,not suiiiciently rigid to afford a satisfactory means for `lifting therolls, particularly .with vvideI rolls.v

Furthermore, itisimportant in fast paper Imaking machines vthat the time'consumed-in .35 y 'the way as rapidly as the paper is produced.

handlingv the -rolls be reduced as far as possible, so that the Vrollsmaybe gotten out of It is the especial object of the present inventionto produce a simple construction for delivering the webv rollifromthewinding mechanism, in Vwhich the `roll is pushed olf the Winder onto areceiver'fromwhich it may j be delivered in any suitable manner.

l-A `further object ofthe invention is to produce such a' constructionwhich can Vbe readily. andeasily operated, and which shall re- ,Y quirea minimum amount o f space.

lWith-these and other objects not specificalv` ly referred to inview,'th e invention consists incertain novel parts,- arrangements andcombinatlons which will be described in connection'with the accompanyingdrawings and thev novel features pointed out in the claims hereuntoannexed.

In these drawings,-

. Figure 1 is a plan view of the improved delivery mechanism, and

Figure 2 is a side View, partly in section, of the construction shown inFigurel.

Referring now to these drawings, the invention consists generally in theprovision of a receiver located, preferably, at one side of the Windermechanism, in combination with a pushing device which acts to push theweb roll from the Winder onto the receiver, the receiver beingthereafter operated to deliver the roll in any desired manner. While thespecific embodiment of the invention may vary widely, in the particularconstruction illustrated there is shown a Winder, mechanism of nconventional form including side frames 1, 2, and a pair ofwinding'rolls or drums 3, 4 suitably journalled in the frames, thesedrums being driven drums rotated in any suitable manner by mechanism notillustrated. The web of paper W, as it comes from the paper makingmachine, is Wound into a web roll 5 on a spindle 5', the roll beingwound by the. winding drums in the usual manner.

. In accordance lwith `the invention, the mechanism for pushing the web'roll oif the winding' drums onto th receiver is located closely adjacentthe Winder drums and, preferably, at the long side of the web roll.,While the pushing mechanism may varysomewhat in construction, a simpleone is that shown,

in which there is provided a shaft 6 suitably supported in, the sideframes, which shaft is provided with a number of arms 7, 8, in which aresupported a pair of pushing spools or discs 9, 10. This shaft isrotatedthrough suitable gearing, indicated at 11, from a m0- tor 12; Onthe rotation of the shaft in the direction of" arrow a in Figure 2, thepushing pushing it from its position on the drums`i'3`,\95

4 and onto a receiver, indicated by the nu- This' receiver may varyWidely in construction, but, as shown, will be locatedadnism and in aposition whereby the roll may be readily pushed or shoved onto it. Inthe particular construction illustrated, this receiver is in the form ofa number of cradle arms 14, 15, which preferably have curved In theparticular construction illustrated,

the roll is lowered by the cradle arms to the floor level, indicated bythe letter F, where the web roll may be moved away for subsequentvhandling. Any suitable means may be employed for operating therock-shaft to cause the arms to deliver the web rolls, but

in the referred construction these means will be suc that the cradlearms after delivering a web roll will return to a position to receive.asuccessive web roll. In the particular con- The operation of thedevice will beclear ,winding machines, the combmation with.

from the foregoing Adescription but may be `briefly summarized asfollows:

Whenthe roll 5 has reached the desired diameter, the web is severed inthe usual manner, and the shaft 6 is rotated by th-emotor 12 through onerevolution, which pushes the roll 5 from the drums 3, 4 onto thereceiver 13,.by means of the spools or discs 9, 10. The shaft havingmade a complete revolution comes to rest in its original position. Theoperator then causes the movement of the rock-shaft 17, which moves thecradle arms from the position shown in full lines in Figure 2 to theposition shown in dotted lines, where the web roll 5 is deliveredontothe Hoor. When the parts have reached this position, the reverslngswitch stops the rotationof the shaft to the right and causes itsrotation to the left to bring the cradle armsv back to the positionshown in full lines in Figure 2. It will be understood, of course, thata limit switch isA or may be employed for stopping the motor 12 after ithas caused one rotation of the shaft 6,. f

With -this construction therefore, the web rolls may be readily andquickly removed from the winding mechanism and delivered as desiredwithout-the necessity of overhead hoist or the use of the spindle formanipulating the rolls. c

While. the invention has been shown and described in its preferred form,it will be understood that various changes -maybe made in the specificconstruction and operation of the parts without departing from ,theinvennexed.
